Atlanta Falcons quarterback Matt Ryan went to the ground with a leg injury in the third quarter against the Detroit Lions. He appeared to hit the deck without even being touched, but upon review, his foot was stepped on by backpedaling tackle Will Svitek. He made his way to the locker room, and will be replaced by Chris Redman.

Here's a video of the play:

Ryan's foot looked to bend sideways at the ankle. This is not good, but it looks like it could be worse.

Trainers surrounded him on the field. He was able to make his way to the sideline with a slight limp without any assistance. Doesn't mean anything definite about whether he'll be able to return for this game, but it's at least a good sign.

Medical personnel checked on him near the Falcons bench before escorting him to the locker room. The best news yet: Ryan was shaking off trainers as they searched for pain in his leg, according to FOX's sideline report.
